GLX65/120/212 Guitar Amplifier with DSP & ChannelTracking  
Congratulations!  
You are now the proud owner of one of the Crate GLX top-of-the-line three-channel guitar  
amplifiers. These rugged amplifiers combine outstanding features with serious clean and distorted  
sounds. An easy to operate DSP section lets you dial in a variety of digital effects including reverbs,  
delays, octave and wah-wahs – with a separate level control. Crate’s unique Channel Tracking fea-  
ture means that as you switch between channels and gains, the DSP automatically “tracks” the  
changes - your DSP settings for each channel are stored and automatically recalled! The supplied  
three-button footswitch allows you to select between the three channels and turn the DSP on and off  
by “remote control.” The top-mounted electronic tuner lets you get tuned and stay in tune any time  
the amplifier is on.  
Like all Crate products, your GLX amplifier is designed by musicians, and built using only the best  
components. Extensive testing confirms that this amplifier is the absolute best it can be.  
In order to get the most out of your new amplifier, we strongly urge you to read this user’s guide  
before you begin playing.  
And thank you for choosing

Channel Tracking:  
Your Crate GLX amplifier gives you the power of Channel Tracking! Once you select a DSP set-  
ting for each channel, Channel Tracking recalls those DSP settings automatically – without chang-  
ing the DSP controls! For example:  
Select the Clean channel. Set the DSP Mode to “8” (slow deep flange w/reverb)  
Select the Overdrive channel, Gain 1. Set the DSP Mode to “10” (slow tremolo chorus w/reverb)  
(the setting for the Clean channel is now saved to memory)  
Select the Overdrive channel, Gain 2. Set the DSP Mode to “14” (touch wah)  
(the setting for the Overdrive
